In his letter, Sir Lindsay said: "As you know, the safety and security of all colleagues is a top priority for me, especially considering the heightened community tensions, significant increase in protest activity and spike in abusive and threatening behaviour towards members.

Yesterday Shadow Chancellor Rachel Reeves slammed aggressive Gaza activists who attacked MPs over the ceasefire vote.
She told the BBC: "I believe in the right to protest, I don't believe in the right to intimidate, and some of those protests… I believe have crossed the line from protest to intimidation.
"Protesting outside people's homes, putting pressure on them in that way I think is totally unacceptable.
"I would urge those people who are conducting those protests, I understand why you call for a ceasefire, but do things in a responsible way and don't intimidate or put pressure in that way on elected representatives or anyone else for that matter."
